Digitize.

Introduction

Digitizing is the first step for analysis after the recorded images have been captured and stored on the hard disk of the computer. The Digitize module is a Windows based program for digitizing images to be analyzed using the Ariel Performance Analysis System (APAS). Digitizing can be performed in one of two modes, either Manual or Automatic.
Manual digitizing is performed under computer control and the digitizing of video images is computer assisted. A trained operator with a reasonable knowledge of anatomy and a consistent pattern of digitizing can rapidly produce high-quality digitized images.
Automatic digitizing requires some sort of visible markers. User input is minimal as the computer automatically tracks the markers based on color, contrast, position, velocity and acceleration.
